Specification of Letters Patent.

Application fild March 13, 1915. Serial No. 14,158.

To all whom it may concern.

Be it known that we, J AMES A. CAMERON and GUs'rAF B. BIRCH, both citizens of the United States, and residents of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and. useful Improvements in Mountings for Rotatable Members, of which the following is a specification. I

The present invention relates generally to means for mounting rotatable members and has more particularly reference to the means for mounting the slitting members in a slitting machine.

The main object of this invention is to insure the rotation of the slitting member at all times when in frictional engagement with its companion and to provide simple and reliable means for edecting this.

Accordingly the invention comprises a rotatable member together with means for supporting thesame which permit the said rotatable member to turn around any one of a number of independent bearing surfaces.

This is accomplished by interposing a floating member between the rotatable member and its supporting means, the said floating member being mounted loosely for rotation on said supporting means and the rotatable member being mounted loosely for rotation on said floating member.

In the preferred form herein disclosed said floating member includes an anti-friction bearing The invention further rovides a carrying member having confining cheeks spaced apart and provided with bearings, together withv a pintle mounted preferably against rotation preferably by means of complementary Webs and slots formed in said carrying member and pintle, thereby preventing lateral displacement of the parts and spreading of the cheeks.

Other features of construction, combination of part and arrangement of elements will appear as the specification proceeds.

In the accompanying drawings the invention is disclosed in a concrete and preferred form but changes of construction may be made from the form shown without departing from the legitimate and intended scope of the invention as expressed in the appended claims.

In the said drawings:

Figure 1 is a side elevation of a slitting member, together with the mean for mounting the same and the companion member against which it works.

Fig. 2 is a top plan view of the slitting member and the means for mounting the same as shown in Fig. 1.

Fig. 3 is a detail view of a slitting member shown mounted in one end of the carrying member and with one of the confiningcheeks removed.

Fig. 4 is a horizontal sectional View on the line 4-d of Fig. 3.

Fig. 5 is a horizpntal sectional 'view through a slitting member and the mean for mounting the same showing a modification."

Fig. 6 is a detail view in elevation of a slitting member and the means for mounting the same, showing another modification.

Fig. 7 is a horizontal sectional view on the line 77 of Fig. 6.

Fig. 8 is a sectional view on the line 8-8 of Fig. 9 SllOWiIlg still another modification.

Fig. 9 is a side elevation of the parts shown in Fig. 8.

Similar reference characters indicate corresponding parts throughout the several views.

The rotatable member is here exemplified by a slitting member 1, here shown as a score cutter, acting against. its companion 2. here shown as a smooth surfaced roller or disk, the device herein being applicable to the score cutter and backing roll shown in Patent No. 1,076,189, it will be understood, however, that the slitting member need not be in the form of a score cutter but may be the companion member 2, that is, a smooth faced roller, and may be employed in a machine such as is shown in Patent No. 904,247.

3,is a carrying member similarin construction to What is shown in said Patents Nos. 904,247 and 1,076,189. This carrying member is preferably provided with confining cheeks 4 spaced a art and having a bearing 5 therein preferably provided with projecting webs 6. 7 indicates the supporting member taking here the form of a pintle which is provided with slots 8 into which the Webs 6 extend whereby said pintle is held against rotation in the bearings 5. Mounted loosely for rotation on said pintle is a floating member 9. In Figs. 1 to 4. this floating member includes an anti-friction bearing comprising in this instance the inner race.

Patented Feb. 12, this.

ring 10, the outer race-ring 11 and the balls 12. Mounted loosely for rotation on said floating member is the slitting member 1.

It will be understood that this construction permits the slitting member when frictionally rotated by its companion 2 to r0- tate around any one of a number of independent bearing surfaces so that if for some reason the parts should become clogged at one point, rotation may still take place at another point. In the present instance the anti-friction hearing will normally afford the least resistance to the rotation of the slitting member and therefore the outer racering 11 will normally rotate on the balls 12. Should, however, for any reason the antifriction bearing become clogged up, the slitting member may rotate around the outer race-ring 11 while the latter remains stationary, or the rotating movement may be be tween the inner race-ring 10 and the pintle 7. Or the movement may be partly around one surface, and partly around another surface.

It will further be observed that the webs 6 and slots 8 serve not only to hold the pintle against rotation but also to prevent lateral displacement of said pintle, thus Providing against accidental removal of the slitting member from its supporting means and also preventing the cheeks from spreading, thereby keeping the slitter member from wabbling.

In Fig. 5 the floating member 13 is in the form of a bronze bushing which is loosely mounted on the pintle 7 and on which is loosely mounted the slitting member 1. In this form the rotation may take place either between the pintle and the floating member or between the floating member and the slitting member.

In Figs. 6 and '7 the pintle 14: is provided with squared end portions 15 which are seated in the slots 16 of the cheeks 4, the floating member 13 being mounted loosely for rotation on the circular middle portion of the pintle 14, and the slitting member being mounted loosely for rotation on said floating member. In this case also the rotation may take place either between the pintle and the floating member or between the floating member and the slitting member.

In Figs. 8 and 9 the bearings in the carrying member 3 constitute the supporting means and are provided with webs 17. The pintle 18 is here provided with annular grooves 19 adapted to receive the web 17. In this form, therefore, the pintle constitutes the floatingmember being free to rotate in its bearings. The slitting member may be mounted loosely for rotation on said pintle,

or a secondary floating member 20 may be interposed as shown.

What is claimed, is:

1. A device of the character described comprising: a carrying member having confining cheeks spaced apart, a pintle having its ends flush with the outer faces of the confining cheeks, said confining cheeks being formed to prevent endwise displacement of the pintle and lateral displacement of the cheeks, and a rotatable member mounted loosely for rotation on said pintle with its opposite .sides engaging said confining cheeks whereby lateral movement of the rotatable member is prevented.

2. A device of the character described comprising: acarrying member having confining cheeks spaced apart, a pintle having its ends flush with the outer faces of the confining cheeks, said confining cheeks and said pintle being formed to prevent endwise displacement of the pintle and lateral displacement of the cheeks, a rotatable member mounted loosely for rotation on said pintle, and a rotatable member mounted loosely for rotation on said rotatable member, said rotatable members having their opposite sides in engagement with said confining cheeks, whereby lateral movement of the rotatable members is prevented.

3. A device of the character described comprising: a carrying member having confining cheeks spaced apart and provided with bearings, a pintle mounted in said bearings, and having its ends flush with the outer faces of said confining cheeks, a floating member mounted loosely for rotation on said pintle, and a rotatable member mounted loosely for rotation on said floating member.

AMA device-of the character described comprising: a carrying member having confining cheeks spaced apart and provided with bearings having projecting web portions, a pintle having its ends flush with the outer faces of the confining cheeks resting in said bearings and having slots'for the reception of said web portions, and a rotatable member rotatably mounted on said pintl between said cheeks and having substantial areas of its opposite faces in engagement with said cheeks, whereby any tendency of the rotatable member to tilt on its axis is overcome.

Signed at New York, in the county of New York and State of New York this 12th day of March, A. D. 1915.
